Title: Apparatus for injecting tires into rotary kilns
Inventor: BIRCHARD RONALD W T
IPC: F27D3/00
Filed: 1993-01-21
Abstract: An apparatus for injecting one or more tires into rotary kilns includes an inner shroud mounted within the kiln shell and shaped to provide a tangential entry path for tires through the shell and into the material being treated, and a gate, mounted externally of the shell and communicating with the shroud for receiving tires and conveying tires to the shroud. The gate also prevents the escape of material and gases from within the kiln and limits the entrance of outside air into the kiln through the apparatus. The shroud preferably opens in a direction facing the opposite of the direction of kiln rotation, thereby minimizing the amount of material being treated which enters the shroud. The shroud also is shaped to limit the protrusion above the level of material being treated within the kiln. The gate includes a counterweighed door and cam actuation means which opens the door when the apparatus is oriented approximately horizontal at a three o'clock position, and closed when the apparatus is oriented substantially vertically at a twelve o'clock position. The door may also be actuated with an external cam. The apparatus includes a table with a double-acting cylinder motor for feeding tires onto the table, and an accumulator conveyor which feeds the table, and an inclined or vertical conveyor which transports tires to the accumulator conveyor.

Title: Hot melt adhesive composition and method
Inventor: DART NORMAN K
IPC: C08L3/02
Filed: 1992-06-10
Abstract: ABSTRACT            HOT MELT ADHESIVE COMPOSITION AND METHOD         A hot melt adhesive composition and method of use thereof is provided. The hot melt adhesive contains a major amount of a meltable saccharide, e.g. a lower alkyl glycoside and a minor amount of a polysaccharide derived from starch selected from the group consisting of pre-gelatinized converted starches, cold-water soluble dextrins, and maltodextrins, and mixtures of more than one of such members of said group. The amount of meltable saccharide is sufficient to provide a flowable melt of said composition and the degree of polymerization and said minor amount of the polysaccharide are sufficient to tackify said melt, but are insufficient to prevent said melt from flowing. Preferred compositions also contain a minor amount of dextrose in addition to an alkyl glycoside. The composition can be used alone as a hot melt or in admixture with other hot melt materials, e.g. ethylene/vinyl acetate copolymers. The composition is advantageously used to bond cellulosic substrates which are, as a result, particularly susceptible to repulping, and thus recycling.

Patent CA-2100378-A1 (CA)
Inventor: GEEHAM CALVIN T
IPC: A61N1/38
Filed: 1993-07-13
Abstract: A device providing performance of CPR without need to exert forces of such magnitude that the patient may be injured, and which further provides performance of defibrillation and ventilation. The CPR assist device according to the present invention is composed generally of an elongate column member, handles mounted normal to the column member, a suction cup member mounted at one end of the column member, and a defibrillation system so that the patient may be defibrillated in conjunction with CPR. According to the method of the present invention, an aid giver places the suction cup member of the CPR assist device on the chest of the patient, then grabs the handles and proceeds to alternately press on the chest and pull from the chest. The suction cup member causes the chest to compress and expand, thereby creating a churning action within the chest cavity that resuscitates the patient. An added benefit of the CPR assist device is that the expansion of the chest cavity as the suction cup member is pulled away from the chest will stimulate lung action of the patient. Defibrillation is provided by the aid giver actuating one or more switches on the column member which supplies electrical stimulation at electrodes mounted to the suction cup member. The defibrillation circuit may operate from household current or may be powered by an internal battery.

Abstract: A magnetic actuator for adjusting the zero and span settings of a transmitter used in industrial process control systems.  The actuator has a single magnet in a housing. The actuator is removable from the transmitter.     When the actuator is unactuated the magnet is in a null position wherein it does not actuate either the zero or span setting reed switches.  The magnet can be moved to either a first position wherein it actuates the zero setting reed switch or a second position wherein it actuates the span setting reed switch.  The actuator applies a torque in the proper direction to return the magnet to the null position when the torque applied to move the magnet to either the first or second position is removed.

Patent CA-2106380-A1 (CA)
Inventor: DUMBLETON JOHN H
IPC: A61F2/36
Filed: 1992-03-19
Abstract: A beam adapted for implantation within a bone is able to support bending and torsional loading forces applied thereto. The beam has a stiffness defined by a modulus elasticity, which stiffness varies along the length of the beam to match the corresponding stiffness of the cortical bone adjacent the beam after implantation within the bone. The beam is made from an elongated core formed of continuous filament carbon fibers embedded in a thermoplastic polymer matrix with the carbon filaments extending in a direction substantially parallel to the longitudinal axis of the beam. Encasing the core is a filler molded to the core, which filler is made up of the same thermoplastic polymer as the core but contains no reinforcing carbon fibers. The filler provides the prosthesis with a shape generally conforming to the desired shape of the final prosthetic implant. A sheath formed of carbon reinforced filament fibers embedded in the thermoplastic polymer is wound in spiral formation around the filler and molded thereto. The winding angle and the sheath thickness along the beam may be varied to vary the modulus of elasticity to match that of the cortical bone adjacent thereto.
